Hugging Face 上悄悄放了 80TB 天文数据，用你笔记本就能跑 SDSS 和 Gaia 交叉匹配。搞 AI for Science 的话别错过，比想象中好上手。
Multimodal Universe 项目在 Hugging Face 上发布 80TB 天体物理数据集，整合了 SDSS 和 Gaia 等 30 多个来源的数据。该数据集包含星系光谱、恒星时间序列及多种物理量，通过交叉匹配技术实现高效查询。用户仅需约 4GB RAM 即可在笔记本上处理 800k 与 122M 个天体的匹配。该发布有望将天文数据的可及性提升万倍。

people are sleeping on the mega-release happening every week in AI x Science on Hugging Face this one is 80TB of astrophysics data - 80TB seriously => https://t.co/e4TGUeg61o Georgia Channing @cgeorgiaw Seems like no one's noticed the 80TB of astrophysics data from 30+ sources that just dropped on @huggingface . ...and you only need ~4GB of RAM to load it. We're talking over 80TB of galaxy imagery taken across the spectrum, spectra of galaxies and stars, time series of variable stars, and a whole zoo of assorted measurements and physical data. And all of it can now be wrangled on your laptop, thanks to Multimodal Universe's just released cross-matching. SDSS x Gaia means you can match 800k objects against 122M objects, and it never climbs above ~4GB of RAM. Huge congrats to @smith42mike for leading this and making the world of astro accessible to probably 10,000x more people.
